Work Experience

Work Experience

  • Staff Software Engineer, Nymbl Systems

    Jun, 2026 - Present

    • Led strategic architecture across three concurrent engineering teams during a complex Angular 21 modernization, establishing a formal cross-functional testing and issue-tracking protocol that delivered a regression-free release with zero hotfixes; minor issues were identified early and clearly communicated to Support and Customer Success so the business could prioritize confidently.

    • Improved operational throughput by identifying and removing a 34-point sprint bottleneck, then driving data-informed capacity planning that shifted execution from feature-factory output to architecture-first customer commitments.

    • Authored and maintained Architecture Decision Records (ADRs) covering OpenSearch, OIDC authentication, and frontend/backend migration architecture, creating a durable record of technical tradeoffs and decisions for cross-team alignment.

    • Developed an AI-driven approach to reverse-engineer legacy code into validated technical specifications, enabling deliberate MVP scope reduction and focus on high-impact delivery targets.

    • Institutionalized a plan-ahead engineering culture through proactive refinement and proof-of-concept discovery, increasing sprint predictability and improving leadership decision quality on scope and off-ramping.

  • Senior Software Engineer, Nymbl Systems

    Jun, 2022 - May, 20263 years 11 months

    • Championed a cross-functional delivery reset for patient-equipment logistics after many missed sprints. Facilitated refinement, aligned engineers and product on workflows and stories, swarmed execution, and used spikes with clear outcomes so the team could architect deliberately and ship together with quality.

    • To scale partner onboarding without duplicating integration code, I led a TypeScript architecture in Node.js on AWS Lambda that established reusable contracts and secure event-driven boundaries, enabling faster and safer delivery of new integrations.

    • When the organization needed a long-term integration strategy, I partnered with the Principal Architect to implement an EventBridge vendor connector model using Lambda Layers and Terraform, reducing marginal onboarding effort per vendor through a repeatable N+1 deployment pattern.

    • To secure inbound vendor communications, I implemented Cognito-based client-secret authentication and tenant-scoped credential configurations, ensuring authenticated access and safe retrieval of external platform data for webhook callers.

    • To unify inconsistent vendor payloads, I built normalization workflows that transformed source-specific data into generic EventBridge events, configuring API destinations and routing rules to persist integration data for core platform visibility.

    • When Lambda artifact constraints blocked deployment, I introduced a 'dummy.zip' strategy for Terraform packaging and pipeline validation, preventing failed deploys caused by upload limits while preserving predictable release behavior.

    • Led the high-stakes architectural migration from legacy AngularJS to Angular 21, engineering a hybrid application shell with specialized CORS authentication flows to support parallel production and beta environments.

    • To accelerate migration velocity, I developed custom AI-assisted extraction workflows (Claude skills) that automated the transition of legacy business logic into shared component libraries and standardized Entity-to-DTO patterns.

    • Supported a teammate delivering a Python AWS Lambda for AI-generated Letters of Medical Necessity (LMN), contributing to integration of generated clinical content into the regulated healthcare platform's documentation pipeline.

    • De-risked high-priority initiatives like the Billing module redesign by facilitating early technical discovery and surfacing architectural constraints, pivoting the team toward more sustainable implementations while coaching peers on API security.

    • Designed a modular guest access mechanism using custom Angular guards and resolvers, successfully decoupling user access from the primary authentication provider for specific workflows.

    • Architected and implemented a shared UI component library and standardized layouts, reducing front-end technical debt and enabling maintainable, repeatable workflows across the enterprise application.

    • Strengthened system integrity by securing API endpoints with Spring Security and integration tests, working closely with Security and QA teams to mitigate vulnerabilities and prevent regressions.

    • Prototyped an extensible HTML-to-PDF library using the Strategy Pattern to evaluate rendering engines, enabling maintainable generation of regulated medical forms and HIPAA-compliant documentation.

    • Architected APIs for auto-populating regulated forms and industry-standard EDI messages, collaborating on strict API contracts to ensure compliance and seamless integration with document services.

    • Translated complex product requirements into technical roadmaps and Jira-ready documentation, bridging the gap between Project Management and Engineering for streamlined execution.

    • Mentored junior and mid-level engineers in Angular best practices and code standards, fostering a culture of high-quality, type-safe development across a large-scale enterprise codebase.

  • Independent Contractor, Traiforce Group LLC

    Nov, 2020 - Jun, 20221 year 7 months

    • Led the design and implementation of a Kafka-based Backend For Frontend (BFF) architecture using single-spa, ensuring scalable, modular, and responsive systems.

    • Rearchitected a React.JS/.Net Core Entity Framework-based healthcare platform, resulting in a 50% reduction in page load time by separating database and business logic layers, allowing for metrics and telemetry to be introduced.

    • Extended an established Java-based near real-time reporting architecture for an eLearning platform deployed in AWS. Integrated serverless, microservice, and monolithic application components to support xAPI launch verbs. Defined future requirements to support the emerging CMI5 specification.

    • Automated 40+ business processes for a state government agency, reducing execution time from 3 months to 2 minutes by collaborating with government statisticians.
